Warrior epic, as iksar. kos near turn ins etc

[syztem]

I am about to finally take all the pieces i have and start from there, I see a lot of turn ins are in EFP and such. I am just curious if anyone has done this as an iksar, or is very familiar with it as to if any kos targets to me are nearby? I know -most- epic NPCs are apphre/indifferent to all. I am more so worried about invising through FP, then trying to check if hes all alone and im free to turn in or what assuming hes all alone since im guessing if hes in war guild or something hes on sep faction.

Any more helpful info, if people had items like wingblade MQ'd did they use invis trick on the non warrior or is none of that required? I will probably be getting hand of maestro MQ'd for sure, as he hasn't wanted to drop it. and I doubt ill be going to sky for a while, but plenty of people seem to have wingblades is why i ask. otherwise I would prefer having it all in my own hand.

Have plenty more non epic questions, such as swift blade of zek, will sapper, wave crasher. I will probably want to go with like swiftblade mainhand, offhand epic for dps? and for aggro, maybe mainhand epic swift offhand despite no proc? I don't have a sapper yet might have to parse what the best dps non aggro, and best aggro of the mix is.
